WLCG HTTP Proxy Discovery

Mandate and Goals

Define the WLCG-wide standards for grid jobs to find out what HTTP proxy or proxies to use

This problem has already been attempted to be solved in many different ways, none of them very completely, for example by CernVM, GlideinWMS, ATLAS site configurator, generator files for ATLAS & CMS, and now the Shoal tool for cloud proxies

Having a standard would make it much easier for new applications to use local http proxy caches
